130f is barely over idle, lmao. if your computer is rebooting, it's probably the CPU or Power Supply, not the GPU. Typically if a GPU has a thermal issue, it crashes the Nvidia driver. CPU and PSU are much more common to spontaneously reboot the PC.

It is possible your PSU can no longer support your GPU (Power Supplies lose capacity over time, and if you were threshold already, it may be tripping like OCP or something)
